Can back pain caused by symptom-giving sacroiliac joint relaxation ...

The thoracolumbar fascia is a very tight
structure that inserts into the spinous
processes of the lumbar spine, into the sacrum
and into the iliac crest and continues further
down as the fasciae of the buttocks and the
lower limbs and laterally as the fasciae of the
oblique abdominal muscles.
The posterolateral aspect of the thoracolumbar
fascia is reinforced by the fascia of the
latissimus dorsi muscle, which constitutes a
link between the pelvis and the upper limbs,
ending at the cranial aspect of the lateral
bicipital groove. Furthermore it extends down
to the inferior angle of the scapula.

The abdominal fascia
In its ventral aspect, the abdominal fascia has
fibres that are crossed over. These fibres are
the continuation of the dorsal fascia, lining the
abdominal wall. Together with the dorsal fascia
they provide for a stable and dynamic pelvic
floor. [35, 58]

The peritoneum [18, 35]
The internal female genital organs are located subperitoneally in the pelvis, behind
the bladder, and in front of the rectum. The uterus with the broad ligament of the
uterus is located in the middle of this space. The uterus itself is partly covered by the
peritoneum, which is firmly adhered to it. Only its lateral parts are linked to the hip
bones exclusively by connective tissue. Recesses formed by the peritoneum ventrally
and dorsally to the uterus enable it to glide in the subperitoneal space:
o the vesicouterine excavation
o the rectouterine excavation (pouch of Douglas)
